Abstract:
Three dimensional finite element modeling of two flexible plates connected by a shear bolted
lap joint is done in order to determine the dynamic characteristics of the model. Energy
dissipation occurs due to friction and micro slip between the contacting surfaces of the plates
when they are subjected to vibrations. Hysteresis curves are drawn to calculate this dissipated
energy under different harmonic loadings.
This work involves use of ANSYS to analyze the three dimensional model. A FE analysis
will be performed on the contacting surfaces to observe the variation in different dynamic
parameters of the joint. And by using Proper Orthogonal Decomposition (POD) concept, the
POM modes will be determined for the system to show how they can be helpful in the
reduction of the model.
